General Aftercare
For Kubota Based Propulsion & Generating Set Engines, Beta Marine Recommend:
Engine Oil
Engine oil quality should have the minimum properties of the American Petroleum Institute “API” classification CF with multi-grade SAE ratings as listed in the following table.
NB: An acceptable alternative is a mineral based, semi-synthetic lubricating oil with a content mix no greater than 30% being synthetic based. Do not mix two different types of oil or SAE rating.
Do not use lubricant additives and/or fully synthetic lubricating oil.
| Ambient Temperature | Multi-Grade Oil |
| -30°C to 0°C | SAE 10W/30 |
| -15°C to +15°C | SAE 15W/40 |
| 0°C to +30°C | SAE 15W/40 |
| 25°C and above | SAE 15W/40 |
Engine Coolant Antifreeze
Always use a Mono Ethylene Glycol Based Extended Life Anti-freeze mixed 30 < 50% with water.
NB: Do not exceed an Anti-freeze mix greater than 50%, as the engine cooling efficiency will be detrimentally affected.
For engine coolant capacity please refer to the relevant engine operator’s handbook. PDF`s can be found within the relevant engine page within this website or visit literature downloads…
Gearbox Lubricants
Depending on the gearbox brand/type they will either require Automatic Transmission Fluid or Gearbox Oil. For type, specification and capacity, please refer to the relevant gearbox operator’s handbook. PDF`s can be found within the relevant engine page within this website or visit literature downloads…
